4-Aminoacetanilide or paracetamin is a chemical compound which is a amino derivative of acetanilide and para-isomer of aminoacetanilide. There are two other isomers of aminoacetanilide, 2-aminoacetanilide and 3-aminoacetanilide. Aminoacetanilide derivatives are important synthetic intermediates in heterocyclic and aromatic synthesis. These derivatives have found applications in pharmaceutical industry and dyes and pigment industry.[1]

Synthesis edit

Becillus cereus converts 4-phenylenediamine to 4-aminoacetanilide.[1][2] Reduction of 4-nitroacetanilide by hydrogenation catalyst generates 4-aminoacetanilide.[3] Green synthesis of p-Aminoacetanilide is achieved by reducing p-nitroaetanilide using Zn/NH4Cl in water.[4] Number of methods are available to reduce 4-nitroacetanilide using different catalyst and reaction conditions.[1]

Uses edit

4-Aminoacetanilide is used as in intermediate in the production of some dyes.[5] 4-aminoacetanilide is also used for the synthesis of beta-lactams.[6]
